this.router.navigate(['action-selection'], { state: { example: 'bar' } });
路由跳转,传入参数。
在目标页面接收参数: 此处需要注意(必须在constructor中获取传参,当从其他地方跳转进页面时,如果没有传参会引起报错。所以需要进行判断)
constructor( private http: HttpConfig, private commonService: CommonService, private notification: NzNotificationService, private ActivatedRoute: ActivatedRoute, private router: Router ) { this.searchParams = this.router.getCurrentNavigation().extras["state"] ? this.router.getCurrentNavigation().extras["state"]["example"] : "" }
